meanest,

To all whom it may concern.

Be it known that I, 'loMoKroHI HANAMMA, a citizen of Japan, residing at Alameda, in the county of Alameda and State of California, have invented certain new and useful Improvements in Lawn-Rakes; and I do de clare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it 1afivpertains to make and use the same.

y invention has for its object to provide a simply constructed and inexpensive, yet a highly eilicient rake intended primarily for use on lawns, the device being so designed as to thoroughly remove leaves and trash, .even

though the surface of the lawn be extremely irregular.

With the foregoing general object in view,

. v the invention resides in the novel features of drawing and,

construction to be hereinafter fully described and claimed, the descriptive matter being supplemented by the accompanying whichforms apart of this specification and in which Figure 1 is a top plan view .of the improved rake; a Fig. 2 is a detail; longitudinal sectionthereof. on the Fig. 3 is a detail transverse section on the plane of the line 22 of plane indicatedby the line 3-3 of Fig. 1;

Fig; 4 is a perspective view of one of the handle which is secured to the center of a transversely vextending rake head. 2 in the form of a wooden bar preferably curved throughout its length as shown, said bar be ing'braced in respect to the handle, as shown ats' r A number of forwardly pro'ectiu% springs s to t e under 4 are securelattheir rear en side of the bar 2, said springsbeing of flat one-piece construction arranged to yield vertlcallyi 7 Although the sprlngs. 4' could well be attached in any suitable manner, this is preferably done by means of nails or screws '5' and staples -6,' said nails. or.

Sheet metal plates 7 are riveted or otherbe employed. Since theseveral springs 4 are of the same length,.the teeth 9 will be positioned on an arcuate line whose rear ends are directed rearwardly and thus the tendency of the trash and thelike being collected is to move to the center of the rake rather than to the endsthereof. J

The improved rake, constructed as above described, is very eflicient for removing trash and leaves from lawns although it is to be understood that the implement may be well used for other. purposes. Regardless of its use, the springs t will exert the necessary tension on the teeth to secure the best results and said springs will permit said teeth to yield vertically as irregularities inthe ground are encountered, thus preventmgthe rake from depositing the material teeth, although anysuitable number could 1 previously collected thereby i'n depressions 1n the surface bein graked.

From the foregoing, it will be obvious that although the improved rake is of extremely simple and inexpensive construction, it will be highly eflicient and durable,

and since probably the best results are attainedby the specific construction shown and described, thls constitutes the preferred form of the device. I wish it understood, however, that within'the scope of the invention; as claimed, numerous minor changes may be made without sacrificing the principal advantages, For instance either .or both the handle 1 and head 2 may be made of metal if required,
